[Beignet] [PATCH] GBE: Merge successive load/store together for better performance.

[Moore, Anthony W]

Hi,

For this patch http://lists.freedesktop.org/archives/beignet/2014-May/002879.html, why are only DWORDs (and floats) enabled for merging? I tried adding 8-bit and 16-bit and saw some significant performance improvement with some of OpenCV's kernels.

+        // we only support DWORD data type merge
+        if(!ty->isFloatTy() && !ty->isIntegerTy(32)) continue;

Thanks!
Tony
